In Hyderabad City buses there is a bus pass option called TAYL tickets (Travel as you like) in there 2 types of rates for Metro deluxe/Express and for Ordinary buses. Rate difference is may be 10 Rs for both tickets. But that will not allow u to get in to A/c buses. If you are new to Hyderabad and u have to go to long distance area Just ask Conductor to give you 70 Rs Travel as you like ticket. This will enable you to board any bus in whole city except A/c.if your bus is not there u can take any bus to nearest point of connecting bus and u can get more buses there to your destination.

the purchased time to Mid night 11.55 PM. if u get a bus pass of TAYL at early morning 3 '0 clock bus just show the ticket to conductor no one can stop you to roam in the city up to Midnight. Tickets available with Conductors and with controllers also in bus stops. This is cheap and Best way to roam in this city. but as traffic is little high u have to spend some time in bus. But take buses only with route No's of 3 digits if Route No is starting with 5000 series that is not valid as that come into district service.
